135574-63-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135574-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,5,7 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 135574-63:
(8*1)+(7*3)+(6*5)+(5*5)+(4*7)+(3*4)+(2*6)+(1*3)=139
139 % 10 = 9
So 135574-63-9 is a valid CAS Registry Number.

Divergent total synthesis of penaresidin B and its straight side chain analogue

Fujiwara, Tomoya,Hashimoto, Kazuki,Umeda, Masanori,Murayama, Saki,Ohno, Yuki,Liu, Bo,Nambu, Hisanori,Yakura, Takayuki

, p. 4578 - 4591 (2018)

The divergent synthesis of penaresidin B and its straight side chain analogue was accomplished by constructing an azetidine ring via SN2 type cyclization of protected 2,3-syn-3,4-syn-4-amino-1,3-dihydroxyhept-6-en-2-yl mesylate and late-stage introduction of an alkyl side chain via olefin cross-metathesis of 4-allylazetidine with readily available terminal alkenes. This synthetic route would be useful to synthesize penaresidin side chain analogues.

Novel and practical asymmetric synthesis of an azetidine alkaloid, penaresidin B

Yoda, Hidemi,Uemura, Takuya,Takabe, Kunihiko

, p. 977 - 979 (2007/10/03)

A novel and efficient asymmetric synthesis of the potent actomyosin ATPase activator, penaresidin B, is described in a short and complete stereoselective manner by featuring the elaboration of the fully functionalized homochiral lactam, which can also be

Synthesis of sphingosine relatives. Part 19. Synthesis of penaresidin A and B, azetidine alkaloids with actomyosin ATPase-activating properties

Takikawa, Hirosato,Maeda, Takeshi,Seki, Masanori,Koshino, Hiroyuki,Mori, Kenji

, p. 97 - 112 (2007/10/03)

Three stereoisomers of penaresidin A 1 and two stereoisomers of penaresidin B 2' (Scheme 5), azetidine alkaloids isolated from the Okinawan marine sponge Penares sp., have been synthesized.In the course of our synthetic study, the correct structure of penarisidin B has been shown to be not 2 but 2'.Natural penaresidin A is either (2S,3R,4S,15S,16S)- or (2S,3R,4S,15R,16R)-1 and natural penaresidin B is either (2S,3R,4S,15S)- or (2S,3R,4S,15R)-2'.
